A new recommendation for assigning ISBNs to ebooks has been out a couple of weeks. I remarked earlier on why this didn't make sense to assign two different numbers to the EPUB ebook and MOBI ebook of the "same" ebook when the only operation was to take the EPUB one and use an automatic software converter (e.g. Calibre) to convert the EPUB ebook into the MOBI ebook. This is mainly done now simply because Amazon does not "read" EPUB, and the publisher has to produce a MOBI version for its Kindle customers. (In a way, this would be like asking a publisher to assign different ISBNs to a hardcover book depending on which bookseller chain store they sell that book in.) The EPUB ebook on the NOOK and the corresponding MOBI ebook on the Kindle "look" the same and have exactly the same HTML/CSS content. It doesn't make sense that they would have a different ISBN simply because one is reading that ebook on a Kindle vs. a NOOK.

The point is: If it's a basically automatic conversion that takes your EPUB ebook and produces that ebook in a different e-format, the ISBN stays the same. However, if one uses features of a particular format to really distinguish the ebook in that format (i.e., there is no simple, automatic way to convert it to another format), a different ISBN should be assigned.

(PDF is a curious exception. It is a fixed, not a reflow, format and is used for printing. There are converters of course that take an EPUB ebook and automatically creates a PDF file. Perhaps they would be useful to send one's EPUB ebook to a POD machine.)

Now there is a new format on the block: KF8 from Amazon. If one publishes an ebook that uses KF8-specific features that truly distinguishes it from the EPUB version, then it's a different ISBN. That makes sense.

CDF (Computable Document Format) may be an upcoming one for math ebooks.

Now some ebooks are being published as apps: iOS vs. Android. Here, the recommendation should be the same: If one starts with the same base version of the ebook (e.g. HTML5) and uses a tool that automatically produces the two different apps (iOS, Android) with the same ebook (HTML5) base, the ISBN would be the same. However, if the publisher uses iOS and/or Android dependent features to distinguish the two version, then it's two ISBNs.

I was sitting outside the Barnes & Noble cafe perimeter with my NOOK Simple Touch. I was using its Read in Store feature, which allows one to read any ebook available for purchase for up to one hour. You have to be physically present in the store with your NOOK connected to that store's WiFi, of course, to do this. At any time before the end of that hour, you can purchase the ebook or just leave it. But you could return the next day and continue reading the same ebook. In front of me were stacks of shelves of books — for convenience I refer to the traditional print editions of books as "books" and their electronic versions "ebooks" — and thinking of the future of publishing.

The first thing that struck was the irony of having to go to a location with books to browse ebooks. There were people in the cafe who were reading books they just took off the shelves that they were just "browsing" in the same way I was browsing ebooks on my Touch. (There were probably more people there with their notebook computers just using the store's free WiFi to browse the internet.) But I was there, as I had gone there before, just to browse (i.e. read) ebooks and I would not even touch a single book.

The second thing that crossed my mind were how alien the books sitting on the shelves in front of me appeared. It was like they should be in a museum, like ancient artifacts. People looked anachronistically odd walking up the shelves and pulling one out and looking inside. It was so much more convenient to read that book on my Touch. I could navigate through it so much better. In fact it was a better reading experience in every way.

I can understand, perhaps, some wanting art and picture books. The Touch could not replicate those very well, But the Tablet might. And math books are not there yet. But MathML is part of EPUB3 (or EPUB 3). EPUB is the core of the ebook creation and everything follows from EPUB. EPUB3 is really a subset of HTML5 (HTML5/CSS3/JS to be technical), so you might say EPUB3/HTML5 is the future of publishing.

Will people still want books? As time goes on, this desire will diminish. The reading devices are that good now. I suppose if someone wanted a book version of an ebook they would (via some program or service) convert the EPUB to PDF and send it to a Print-On-Demand (POD) machine to spit it out.

I don't know what will happen to the store with books. I don't think it has many years left. A big part of the bookstore itself isn't even books anymore. It's toys and other non-book gift items. And there is a section just selling NOOKs, of course. Maybe there will still be a store without books in the future where people go just to browse ebooks.

For Flipboard, as for Currents, you could add a blog to your Google Reader (which is available to both Flipboard and Currents) and subscribe to there. With Currents, you can do more on the publishing side (via producer) than the RSS feed. Plus it runs on Android too.

When you think about this, it* doesn't make much sense. It says that the EPUB and MOBI versions should have a different ISBN. But EPUB and MOBI are mostly interconvertable (it's basically a reformatting -- the same HTML and CSS is there) and do the same things (EPUB is a superset, really). Suppose you have an Android tablet and you get an EPUB ebook. In the software of the tablet one could have an embedded converter — like calibre calibre-ebook.com — that automatically converts the EPUB to a MOBI and you could be reading the ebook in a MOBI reader on that device vs. an EPUB reader on the same device that would look the same. Would you expect to see the MOBI ISBN on the copyright page or the EPUB ISBN? Only a fairly simple software transformation has been made.

Also I just got an ebook from Smashword smashwords.com and I got them in a bundle of formats: MOBI, EPUB, PDF, RTF, PDB, LRF, ... . What this recommendation says is that each one gets a different ISBN. (This was not the case, of course. It was the same ISBN on both the EPUB and MOBI versions, just as you would expect.) If someone sells their ebook in a bundle of formats like on Smashwords then there should be a different ISBN on each format? I don't think so.

I think the confusion is that the electronic world is not the print world. Just because there are different ISBNs on hardback and paperback (and those two from ebook), that analogy doesn't go over into the e-world since different e-formats can be automatically transformed from one to another, possibly in the reading device itself.

So the recommendation of different ISBNs for EPUB and MOBI is a bad one.

What I think will happen in practice for an e-publisher who is EPUB-based is that they would be able to sell their ebook (.epub) in the Nook Store, iBookstore, Google Bookstore, etc. with the ISBN (eISBN) they assigned to that ebook, but when it came to putting it in the Kindle store would let Amazon put an ASIN on it (as Amazon continues to be outside the EPUB standard).

Here is the best researched guide I've found to the question of how to copy to your ereader an ebook you may have purchased from an ebookstore — represented as an ACSM ("Adobe Content Server Manager") file — that ultimately appears in Adobe Digital Editions on your computer:
